Phone camera and teeshirt selfies

So I wear lots of geeky teeshirts. Many of these shirts have text on them. Maybe it is just me, but I want the text to be oriented the correct way when I take a photo of it. (You all are smart people, so it is not that I think you would be unable to read it backwards. More likely I do not want to appear cluelessly unobservant about what I am posting.)

Originally I tried to take this photo with Instagram. And then I realized the text was backwards. So I pulled up Facebook and took the same photo. Facebook flipped the backwards photo so that the text was correct. It did a face recognition thing prior to taking the photo.

What mystifies me is that Instagram, the king of cellphone photo sharing does not already do this? And that Facebook who also owns Instagram does. I can rotate the photo to its side or upside down, but not flip it over. Probably I could find another app to do this, but now that I know Facebook takes it correctly maybe I will not bother.

Once Facebook has taken the photo and oriented it, I can then go back and use Instagram to post it. This cumbersome method will bother me until Instagram works out how to correctly take the photos. Kudgy workarounds make me hyper-aware I should seek an alternative.
